possible.<
Electric Power Steering
EPS
The concept
The electric power steering is a direct,
sporting steering system that is speed-sen-
sitive.
Power support is reduced with an increase
in driving speed.
Indicator lamp
The indicator lamp stays lit:
The system has malfunctioned or is
faulty.
Please have the system inspected by the
nearest BMW center.

val or the sensitivity of the rain sensor
Intermittent operation
Not on vehicles with rain sensor.
You can set the wipe interval over four
stages with rotary dial 5.
In addition, the wipe interval is varied auto-
matically depending on road speed.
Rain sensor
The rain sensor is positioned on the wind-
shield, directly behind the interior rearview
mirror.
To activate the rain sensor:
>With the ignition key in position 1 or
higher, move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in
position 1, it is then only necessary to acti-
vate the rain sensor. To do this
>turn rotary dial 5 briefly.
To adjust the sensitivity of the rain sensor:
turn rotary dial 5.
To deactivate the rain sensor:
return lever to position 0.
Turn the rain sensor off in automatic
car washes. Failure to do so could
result in damage caused by undesired
wiper activation.<
Normal wiper speed
When the vehicle is stationary, the wipers
automatically switch to intermittent wipe,
not on vehicles with rain sensor.
Fast wiper speed
When the vehicle is stationary, the wipers
operate at normal speed, not on vehicles
with rain sensor.
Cleaning windshield and headlamps*

1Cleaning windshield and headlamps
*
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. For this reason, use an anti-
freeze agent. Refer to page 83.
Do not use the washers when the reservoir
is empty. Otherwise damage to the washer
pump could result.<
Cleaning the windshield
The system sprays washer fluid against the
windshield and activates the wipers for a
brief period.
Cleaning the headlamps
When the vehicle's lighting system is
switched on, the headlamps are cleaned at
reasonable intervals.
Windshield washer nozzles
The windshield washer nozzles are heated
automatically
* in ignition position 2.

Lamps

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps to signal the
position of the vehicle when it is parked.
For information on lighting on one side of
the vehicle for parking, which is available
as an additional feature, refer to page 47.
Low beams
When you switch off the ignition
with the low beam headlamps on,
only the parking lamps will remain
on.
Defective bulbs
The indicator lamp lights up:
At least one bulb of the vehicle's
exterior lighting has failed.
For replacing bulbs refer to page 88.
Follow me home lamps
When you activate the headlamp flasher
after parking the vehicle and switching off
the lights, the low beams will come on for a
brief period.
You can also have this function acti-
vated/deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after
having turned the ignition key to position 0,
you will hear an acoustic signal for a few seconds to remind you that the lamps have
not been switched off
.
Daytime driving lamps*
If you desire, the light switch can be left in
the second position:
When the ignition is switched off, the exter-
nal lighting is also switched off.
You can have the activation settings
for the daytime driving lamps pro-
grammed on your vehicle.<
Automatic headlamp control*
When the switch is set to this posi-
tion, the system automatically acti-
vates and cancels the low beams in
response to changes in ambient light, for
example in tunnels, at dusk, and when it is
raining or snowing.
The vehicle's external lights remain
on constantly when you switch on the
front fog lamps after the headlamps have
come on automatically.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgement in determining when the vehicle
lights should be switched on. For example,
the sensors are not able to detect fog. To
avoid safety risks, you should respond to
these kinds of low-visibility situations by
switching the headlamps on manually.<
You can have the sensitivity of your
vehicle's automatic headlamp control
adjusted.<

Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system:
approx. 3.2 quarts/3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 quarts/5 liters.
Fill with water and, if required, with an anti-
freeze agent according to the manufac-
turer's recommendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agents for the washing
systems are highly flammable. For
this reason, keep them away from sources
of flame and store them only in their original
containers. Store them so that they are
inaccessible to children. Comply with the
instructions on the containers.<
Engine oil
Engine oil pressure
The indicator lamp lights up in red:
Stop the vehicle immediately and
switch off the engine. Check the
engine oil level and top off as required. If
the oil level is correct, please contact the
nearest BMW center.
Do not continue driving, as the engine
could sustain serious damage from
inadequate lubrication.<
Engine oil level
The indicator lamp lights up in yel-
low while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not
drive more than 30 miles/50 km before
refilling.
The indicator lamp lights up in yel-
low after the engine has been
switched off:
Add engine oil at the earliest opportunity,
when you stop to refuel.
Engine oil sensor
The indicator lamp lights up in yel-
low within 20 seconds after the
engine is started:
The oil level sensor is defective. Please
have it checked by a BMW center.
Checking the oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil level should be between the two
marks on the dipstick
6.Return the dipstick to the guide tube,
inserting it as far as it will go.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.

Replacement procedures
Onboard tool kit
The onboard tool kit is stored in a tool
pouch. It is located in the luggage compart-
ment beneath the floor panel.
Windshield wiper blades
1.Fold the wiper arm completely out from
the windshield
2.Position the wiper blade at an angle and
pull the release spring, see arrow
3.Fold the wiper blade down and unhook
it toward the windshield
4.Pull the wiper blade past the wiper arm
toward the top

Lamps and bulbs
The lamps and bulbs make essential contri-
butions to the safety of your vehicle. There-
fore, comply fully with the following instruc-
tions during bulb replacement. If you are
not familiar with the procedures, BMW rec-
ommends that you have your BMW center
carry out the work.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the ser-
vice life of the bulb. Use a clean cloth,
paper napkin or a similar material, or hold
the bulb by its metallic base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical sys-
tem, switch off the electrical acces-
sory you are working on or disconnect the
cable from the negative terminal of the bat-
tery. Failure to observe this precaution
could result in short circuits.
To prevent injuries and damage, always
comply with any instructions provided by
the bulb manufacturer.<

H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and protec-
tive gloves. Failure to comply with these
precautions could result in physical injury if
the bulb is damaged.<
1.Turn the bulb holder to the left and pull
out
2.Remove and replace the bulb
3.Install in the reverse order.
When cleaning the headlamps,
please observe the instructions in the
Caring for your vehicle brochure.<
Xenon lamps*
The service life of these bulbs is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. If one of
these bulbs should nevertheless fail, it is
possible to continue driving with great cau-
tion using the fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high volt-
ages involved, any work on the xenon
lighting system, including bulb-changing,
should be carried out by technically quali-
fied personnel only. Otherwise, there is a
risk of fatal injury.<
